DETAILED DESCRIPTION OF THE INVENTION

With reference now to the drawings, and in particular to FIGS. 1 through 6 thereof, a new golf club device embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral 10 will be described.

As best illustrated in FIGS. 1 through 6 , the modular golf club assembly 10 generally comprises a plurality of golf club shafts 12 that each has a first end 14 and a second end 16. Each of the golf club shafts 12 is elongated between the first end 14 and the second end 16 to a length ranging between approximately 40.0 inches and 45.0 inches. Additionally, each of the golf club shafts 12 has a grip 18 extending from the second end 16 toward the first end 14. The grip 18 on each of the golf club shafts 12 may be comprised of a resiliently compressible material for enhancing comfort while gripping said grip 18.

A plurality of couplers 20 is each disposed on a respective one of the golf club shafts 12. Each of the couplers 20 has an upper end 22, a lower end 24 and an outer wall 26 extending between the upper end 22 and the lower end 24. The outer wall 26 is continuously arcuate about an axis extending between the upper end 22 and the lower end 24 such that each of the couplers 20 has a cylindrical shape. Each of the couplers 20 has a coupler well 28 extending through the upper end 22 toward the lower end 24. The coupler well 28 in the upper end 22 of each of the couplers 20 slidably receives the first end 14 of a respective one of the golf club shafts 12.

The outer wall 26 of each of the couplers 20 has a first portion 30 that has a diameter that is greater than the diameter of a second portion 32. The upper end 22 is associated with the first portion 30 and the lower end 24 is associated with the second portion 32. The outer wall 26 corresponding to the second portion 32 has a channel 34 extending inwardly on the second portion 32 and the channel 34 extends around a full circumference of the second portion 32. The channel 34 has a bounding surface 36 and the bounding surface 36 is concavely arcuate with respect to the outer wall 26 corresponding to the second portion 32. The channel 34 is positioned closer to a threshold 38 of the first portion 30 than the lower end 24. Additionally, an intersection between the outer wall 26 corresponding to the second portion 32 and the lower end 24 is chamfered.

A plurality of golf heads 40 is provided and a respective one of the plurality of golf heads 40 is releasably attachable to a respective one of the golf club shafts 12. In this way the respective golf head 40 and the respective golf club shaft 12 defines a golf club 42 that can be employed for playing the game of golf. Each of the golf heads 40 has a hosel 44 extending upwardly from a body 46 of a respective golf head 40. Furthermore, the plurality of golf heads 40 includes a set of iron golf heads 48, a set of wedge golf heads 50 and a set of driver golf heads 52. The body 46 of each of the iron golf heads 48 is structured in the convention of a respective iron ranging between a four iron and a nine iron. The body 46 of each of the wedge golf heads 50 is structured in the convention of a respective one of a pitching wedge, a gap wedge, a sand wedge and a lob wedge. The body 46 of each of the driver golf heads 52 is structured in the convention of a respective one of a three wood, a five wood and a driver.

The hosel 44 of each of the golf heads 40 has a distal end 54 with respect to the body 46 and the distal end 54 has a hosel well 56 extending toward the body 46. The hosel well 56 in the distal end 54 of a respective one of the golf heads 40 insertably receives the lower end 24 of a respective one of the couplers 20 having the threshold 38 of the first portion 30 of the respective coupler 20 abutting the distal end 54 of the hosel 44 of the respective golf head 40. The hosel well 56 has a bounding surface 58 and the hosel 44 has a plurality of openings 60 each extending through the through hosel 44 and through the bounding surface 58 of the hosel well 56. The openings 60 are spaced apart from each other and are distributed around the hosel 44. An outer surface 62 of the hosel 44 has a recess 64 extending from the distal end 54 toward the body 46 and the recess 64 has a lower bounding edge 66.

A plurality of engagements 68 is provided and each of the engagements 68 is slidably integrated onto a respective one of the golf heads 40. Each of the engagements 68 releasably engages a respective one of the couplers 20 on a respective one of the golf club shafts 12 for releasably retaining the respective golf head 40 on the respective golf club shaft 12. Each of the engagements 68 comprises a sleeve 70 is slidably positioned around the hosel 44 of the respective golf head 40. The sleeve 70 has an inside surface 72 and the inside surface has a lip 74 which extends away from the inside surface 72 and which extends around a full circumference of the inside surface 72.

Each of the engagements 68 includes a biasing member 76 that is positioned between the lip 74 and the lower bounding edge 66 of the recess 64 in the outer surface of the hosel 44 of the respective golf head 40. The biasing member 76 biases the sleeve 70 upwardly on the hosel 44 of the respective golf head 40 into a locking position. Conversely, the sleeve 70 is urgeable downwardly on the hosel 44 of the respective golf head 40 into an unlocked position. Each of the engagements 68 includes a plurality of balls 78 that is each of the balls 78 is positioned between the lip 74 and a respective one of the openings 60 in the hosel 44 of the respective golf head 40. The lip 74 urges each of the balls 78 to extend partially through the respective opening when the sleeve 70 is biased into the locking position such that each of the balls 78 engages the channel 34 in the second portion 32 of a respective coupler 20 for retaining the respective coupler 20 in the hosel well 56. Conversely, the lip 74 is displaced from the balls 78 when the sleeve 70 is urged into the unlocking position thereby facilitating the balls 78 to disengage the channel 34 in the second portion 32 of the respective coupler 20 to facilitate the respective coupler 20 to be removed from the hosel well 56.

In use, the coupler 20 on a respective one of the golf club shafts 12 is inserted into the hosel well 56 in the hosel 44 of a respective one of the golf heads 40. In this way a single golf club shaft 12 can be employed in conjunction with any of the golf heads 40. Thus, a full set of conventional golf clubs does not need to be carried during the game of golf, but rather only the plurality of golf heads 40 and the golf club shafts 12. The plurality of golf heads 40 is interchangeable on the golf club shaft 12, depending on the type of golf club 42 that is required for a particular golf shot. In this way the plurality of golf heads 40 and the golf club shafts 12 facilitate all types of golf shots to be accomplished during the game of golf.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.

Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
